On Sunday, August 24th, comic book lovers across the world held their breath to watch how much crazy collectors would pay for a rare Superman comic book. Though bids   above the initial asking price of 1 million dollars had been coming in gradually since the copy was placed on the auction site   eBay on July 14th, things really started to heat up during the final minutes when the price jumped from $2.5 to $2.6 and then $2.7 million, before shooting up to unbelievable 3,207,852 dollars! This of course was no ordinary Superman comic book, but an edition of the extremely sought-after   No. 1 of Action Comics series -- the first publication of the superhero that was born from the creative minds of teenagers Joe Shuster and Jerry Siegel. Though Action Comics No. 1, which depicted a diaper-clad baby Superman lifting furniture, had a print run of 200,000 copies, only about 100 are known to exist today. While the rarity is certainly a reason for the high price, Stephen Fisher, CEO of ComicConnect.com, thinks it also has a lot to do with the fact that Superman was the world's first superhero! Even so, none of the copies have been able to fetch   as much as the most recent one, simply because they have not been as well-preserved. Graded a rare 9 out of 10 by CGC, a third party grading service for comic books, the book is the highest rated copy of Action Comics No. 1 so far. According to CGC officials, the 76-year-old comic book looks and feels as though it has just come off the newsstand  . That is not surprising given that the original owner, a Virginian man who bought the book for only 10 cents in 1938, had carefully tucked it away   in a wooden box for four decades. Fortunately, when he passed away, the book was bought by a string of collectors who all realized it was a rare treasure that needed to be looked after. Before this, the highest price paid for an Action Comics No. 1 had been $2 million for a copy sold by Hollywood actor Nicholas Cage in 2011. Ironically, the two teenagers responsible for creating Superman... What do we know about the creators of Superman? A) They didn't want to sell the rights to a comic book publisher. B) They knew all along Superman would be the most successful comic book. C) They were professional comic book writers when they created Superman. D) They didn't make much money from creating Superman.

Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person's sense of _ with mobile devices. To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system. Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries. Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom. Over the course of the study, participants received occasional text questions from the researchers that asked "How happy are you?". Along with recording their response, the app used the mobile device's built-in GPS to keep track of the participant's location. The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being. The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today's active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a... The best title of the passage is most likely to be "  _  ".
